Further objects and advantages of the present
invention will be apparent from the following
description, reference being. had to the accom
panying drawing, wherein a preferred form of the
present invention is clearly shown.

ing apparatus constructed according to the in
vention and shown mounted on or suspended from.

a wall of a room or o?ice;
Fig. 2 is an enlarged vertical i sectional view
through the refrigerating apITaratus shown in
Fig. 1 and taken on the line 2—2 thereof; and

wall II_ in any suitable and‘ well-known manner. V15
To hold casing i2 in parallel vertical alignment
with wall H I provide a spacer 22, preferably con- structed of soft resilient material so as not to mar
or damage the wall, which is secured in any suit
able manner to the lower portion of the back wall 20
I8 of casing l2. Mounted upon and extending
outwardly from the front of casing l2 there is
provided a nozzle 24 and a button 25 for operat
ing a valve 26 which controls the flow of water
through the nozzle 24. A drain receptacle or 25
can 21 is positioned below the button 25 and
nozzle 24 and is also carried by the casing l2.
The valve v26, nozzle 24 and button 25 construc
tions are fully described and shown in the patent
to Donald H. Reeves No. 1,923,585 issued August 30
22, 1933 and a description of these structures is
herein unnecessary.

Water to be cooled ?ows from the demijohn l5
into a receptacle 3| having a pipe connection'32
with the valve 26. The pipe connection 32 is in 35
the form of a. coil of pipe or conduit disposed in
a tank or reservoir 33 having suitable insulating
material 34 surrounding same. The closed re
frigerating system within casing l2 includes a
40 casing or housing thereof and its supporting ar- . combined motor-compressor unit 36 supported 40
rangement on a wall.
by springs 31 on a horizontally disposed plate 38
Referring to the drawing, for the purpose of p which plate is welded or otherwise firmly secured
illustrating my invention, I have shown in Fig. 1 ' to the back plate ll! of casing l2. Operation of
vthereof a water or beverage cooling apparatus or compressor unit 36 withdraws evaporated or
45 device, generally represented by the reference
gaseous refrigerant, through a conduit 39, from 45
character IO', secured to a wall II of a'room or the evaporator or cooling element 40 located above
office. The apparatus l0 comprises a casing I2 the unit 36 and within tank 33. The evaporated
which encloses and supports a plurality of ele- . refrigerant is compressed and forwarded under
ments of a refrigerating system to be presently pressure, through a conduit 4|, to a condenser 42,‘
50 described. Casing I2 is substantially D-shaped located below the unit 36 where it is cooled and 50
1 ' in horizontal cross-section and its lower portion
lique?ed. The lique?ed refrigerant ?ows from
is tapered toward the wall" I I as at l3. The upper condenser 42 into a receiver 43 where it is stored
edge of the casing I2 is ?at and receives a cover prior to its ?ow through conduit 44 into evapo
plate I4 which has supported thereon, in an in
rator 40 under control of an expansion device or
verted position, a demijohn I5 adapted to con
valve 45. A ba?le member 46 is securedto back 55

plate l8 of casing 12 and directs air, blown there
into by a fan 41, operated by an electric motor
48, over the condenser 42 and over the motor
compressor unit 36 to cool these elements. The
fan 41 draws cool air into the casing [2 through
openings at the bottom of the casing provided by
, the louvres l1 and this'air, upon leaving the ba?ie
or shroud 46 or after having passed over the
motor-compressor unit 36, ?ows upwardly around
10 the insulated tank‘33 and out of casing I2 through
the openings provided by the louvres I‘! located
erating system including an evaporator for cool
ing beverage adapted to ?ow through said ap
paratus, said refrigerating system also including
a motor-compressor unit and a condenser, means
for circulating air over said condenser, said
means and said condenser being positioned below
said unit and said unit being located below said ’
evaporator, a casing enclosing and supporting
said refrigerating system, said casing having a
plurality of openings in the lower portion thereof 10
and a plurality of openings in ‘the upper portion
in each side of the top portion thereof as shown _> thereof, ba?ie means within said casing for di
by the arrows in Fig. 2 of ‘the drawing. The ' recting air drawn into the lower portion of said
motor-compressor unit 36 is under the control of
15 a suitable switch 5| mounted on the underside of
baffle plate 38. The switch 5| is actuated by
changes in pressure of a volatile refrigerant con
tained in a thermostatic system including a bulb
52 secured to the water coil 32 and responsive to
20 thetemperature of water in the coil. The motor
48 is connected with switch 5| in such manner
that it is caused to operate each-time the motor
compressor unit 36 is'operated in order to drive
the fan 41 so as to cool refrigerant being circu
25 lated through condenser 42.
Obviously there
fore the refrigerant liquefying and circulating
unit is intermittently operated to maintain the
evaporator 40 of the refrigerating system between
predetermined temperature limits.
Since the elements of the refrigerating system
are small and the evaporator.“ is consequently
of low refrigerating capacity the tank 33 is pref
erably ?lled or partially ?lled with a solution or
mixture designated at 54 ‘in which the water
' cooling coil 32 and evaporator 40 are immersed to
thereby provide a temperature holdover and to
increase the cooling capacity of the refrigerating
system. This mixture or solution 54 may be
butyl-stearate ' with 5% carbon tetrachloride
40 which congeals between 45° and 56° F. Benzol
(CsHs) which congeals at about 42° F, or any
other suitable chemical solutions may also be
employed in tank 33 as temperature holdover so
lutions.

The compactness and arrangement of the sup
ports for the elements of the refrigerating sys
tem permit the elements to be disposed one above
the other in substantially vertical alignment so
as to be receivable in the relatively small hous
50 ing or casing l2. The arrangement ‘of the ele
ments of the refrigerating system in casing 12
permits an'e?icient air circulation thereover and
provides a small apparatus of light weight which
is portable and which may bev readily removed
55 from its suspended position on the wall by a
single serviceman.
The apparatus is small in
overall dimensions and therefore resembles a
drinking fountain of the type ordinarily built
into a wall of a room. My improved wall suspen
60 sion type beverage cooling and dispensing ap
paratus permits movabi'lity thereof as a unitary
structure and replacement by another apparatus
in a minimum of time by a serviceman so as notv
to deprive the user of the apparatus of cool
65 drinking water over any appreciable length of
vtime during the servicing or replacement of the
apparatus.
.
